The endpoints of WX are W(2,-7) and X(5,-4).

What is the length of WX?

To find the length of WX, we can use the distance formula:

Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

In this case, the coordinates of W are (2,-7) and the coordinates of X are (5,-4).

Plugging in the values, we get:

Distance = sqrt((5 - 2)^2 + (-4 - (-7))^2)
= sqrt(3^2 + 3^2)
= sqrt(9 + 9)
= sqrt(18)

Since sqrt(18) cannot be simplified further, the length of WX is sqrt(18) or approximately 4.24.
